Yes, absolutely. As a specialized planter box factory, we regularly produce long, narrow planter boxes designed specifically for balcony railings. This is one of our most requested custom projects, and we have extensive experience in crafting boxes that fit your exact railing dimensions, whether you need a sleek 36-inch or a full-length 6-foot profile.

Our standard approach for railing planters includes tailored measurements to ensure a snug, secure fit—no wobbling or sliding. We use weather-resistant materials like powder-coated steel, aluminum, or treated cedar to withstand sun and rain, and we can adjust the depth to accommodate your preferred plants, from shallow succulents to deep-rooted herbs. Each box is built with integrated brackets or a mountable lip that hooks directly onto your railing, making installation simple and stable.

To get started, just provide your railing width, depth, and preferred color or finish. Our factory team will produce a single prototype or full batch with quick turnaround. We also offer drainage holes and optional self-watering systems to keep your balcony garden thriving. Contact us today with your specifications, and we will deliver a perfect custom planter box tailored for your balcony railing.
